Texas Instruments TPS23753A IEEE 802.3-2005 PoE Interface and Isolated Converter Controller with Enhanced ESD Ride-Through TPS23753APW

The TPS23753A is an IEEE 802.3at compliant Power over Ethernet (PoE) interface and isolated converter controller designed for applications requiring enhanced ESD immunity. It supports a maximum output power of 13 W and is optimized for isolated converter designs, making it suitable for powered devices such as VoIP telephones, access points, and security cameras. This device features a robust 100-V, 0.7-,Ѷ hotswap MOSFET and offers programmable frequency with synchronization capabilities. It includes multiple input-voltage ORing options, allowing for flexibility in power source selection. The TPS23753A operates over a wide junction temperature range of -40¬8C to 125¬8C and is packaged in a compact 14-pin TSSOP format. The controller incorporates a bootstrap start-up mechanism and provides cycling overload fault protection without significant power loss. Additionally, it features enhanced ESD ride-through capability, rated for 15-kV and 8-kV system-level ESD protection, ensuring reliable operation during ESD events. The device is supported by application notes for design procedures and adapter ORing, facilitating easier integration into various projects.
